Water Behind Liner

[jrv331]

I saw a posting earlier, naturally cant find it now, about running water behind the liner to remove wrinkles. Just exactly how does that work? How is the water supposed to get out from behind the liner if its tight against the pool wall. Gonna try to pull some wrinkles out this week before closing.
Thanks

John,
on an IG pool, usually, people float (run water behind) their liner to get it to lift enough to re-seat the bead into the receiver when it pulls out - once the water drains, the liner will push back in place on the wall and floor.
your pool is not sealed behind the liner and he water will naturally drain itself (gravity) out.
